NARBOW-FABRIG-LOOM SHUTTLE.

Application filed August 4, 1921.

To all whom it may concern:

Be it known that I, WILLIAM J. MALONE-Y, a citizen of the United States,residing at Ansonia, county of New Haven, State of Connecticut, haveinvented an Improvement in N arrow-Fabric-Loom Shuttles, of which thefollowing is a specification.

This invention relates to loom shuttles and particularly narrow fabricloom shuttles such as are used for the manufacture of Suspender wedding,tapes, ribbon, surgical webbing, garter and armband webbing, elasticfrill web and so forth.

An object of the invention is to yieldingly place the filling or weftyarn in the webbing or ribbon, so as to break the sudden throw of thethread: in the shuttle against the edge ofthe web. I g

It is also an object of the invention to provide a shuttle which may beadjusted to give a tight or round edge on one side and a loose or frilledge on the other side.

It isa further object of the invention to provide a shuttle which may beadjusted to make two round edges exactly alike.

In my preferred construction these objects are accomplished by mountinga shuttle eyes-or guide in a ball yieldingly mounted in the groovedfront part of the shuttle and also providing adjustable means by whichthe ball and the eye can be made stationary at any point within the slotin the front partof the shuttle.

In connection with a more detailed description of the inventionreference is had to the accompanying drawings illustrating the.preferred form thereof, and in which;

Fig. 1 is 'a plan view of a shuttle comprising my invention;

Fig. 2 is a transverse central section thereof;

r Fig.- 3 is a longitudinal central section;

Fig. 4: is'a front edge view;

Fig; 5 is a detail perspective view of one of the adjustable stops forthe ball, and

Fig. 6 is a sectional View of the ball.

In the form of shuttle illustrated, the body 10 thereof is provided witha bowed front portion 11, the usual guide 12 for the shuttle block, andthe rack 13. Within the opening formed by the base and front portions ofthebody is mounted the bobbin or spool 14 which carries the supply offilling thread, it being mounted on the wire spindle 15 removablymounted in the shuttle in reicesses at the opposite ends thereof in theSpecification of Letters Patent.

Serial No. 489,789.

opposite ends of a spool or bobbin are the guiding eyes 16 and 17secured to the ends of light springs 18 and 19 mounted within the body..Mounted in back of the bobbinis av brake 2O bearing against the threadand pivotally mounted in the body at 21. This brake is pressed againstthe thread by means of a spring 22 and preventsthe thread unwinding toorapidly. The construction so far described is usual in thistypeofshuttle.

The front curved or bowed portion of the body is provided with two slots23 and 24 and between the two within the front portion is mounted theball 25. This ball fits loosely within the body portion so that it isfree to turn therein and maymove back and forth. A guiding tube 26extends diagonally through the ball to form a guiding eye-for thethread. This tube is secured in the ball by any suitable'means such asset screw 27. On substantially opposite diagonal points the ball isprovided with eyes 28 and 29 to which are secured light coil springs 30and 31, these springsextending through suitable guiding tubes 32 to thebase of the body portion where the other ends of the springs are firmlysecured by any suitable means as wedges or plugs 30. WVithin the bowedfront portion of thebody, on opposite sides of the ball, are adjustablymounted clamping and limiting rings 33 and 3 1. These rings arepreferably made of wire provided at one side thereof with two spacedparallel supports 35 bent substantially at right angles to the body ofthe ring and they may be strengthened by soldering at the bend b ifdesired. These supports are adapted to straddle screws 36 and 37threaded into the inner wall of the closed portion adjacent the oppositeends of the slot 24. Beyond the screws, the body is provided with twoopenings 38 through which the'free ends of the supports 35 may extend.-By loosening either or both of the through the eye 39, yieldinglymounted guiding eyes 16 and 17, and then through tube-26 from the innerend thereof-emerging away from the ball allowing it to yie from theouter free end at the front curved portion of the shuttle.

In operation, the clamping and limitlng rin 33 and 34 may be adjusted toany position according to the effect desired. If they are spaced awayfrom the ball 25, as shown in Fig. 3 of the drawing, the ball will beyieldingly mounted within the bowed front portion 11 by means of springs30 and 31, and a tension either to the right or left will turn the ballaccordingly or may move the ball bodily against one of the rlngs 33 0134according to the amount and direction of the pull thereon. It will beapparent that, if one of the rings 33 or 34 is spaced a greaterdistancefrom the central or neutral position than the other, that theguide or eye 26 will yieldmore when the shuttle is reversed at oneendvof its travel than at the other, thus giving different effects onthe opposite edges of the fabric. It will be clear from this that, underthe normal conditions where a stationary guide corresponding to theguides 26 is employed, nonuniform edges are liable to be produced. Withmy form of shuttle, adjustments may be made to counteract the unequalconditions to be I met.

Again, if it is desired to form different edges on the opposite sides ofthe fabric, as for instance, a frilled edge on one side and a round edgeon the other, one of the rin s 34 may be advanced to prevent the shutt eball 25 moving toward that side of the shuttle, but the other ring maybe s aced h toward this side.

Further, the shuttle may be employed the same as the present shuttles inwhich the guide or eye 26 is stationary in the center. of the shuttle.This may be accomplished b moving the rings 33 and'34 toward the ba 1 25an clamping it in the central position. It will also be apparent that bythe same means the ball 25 may be secured stationary at any point withinthe curved front 11 by moving it to the position desired and thenclamping it therein by means of the rin 33 and 34. An arrangement suchas this will give a tight ed e on one side and a loose edge on the otherecause, as the guide 26 is not in the center of the shuttle, the samethrow is not obtained on the two sides ha i 1 cause the shuttle travelsthe same distance each time.

- In forming a frill edge with the shuttles at present employed in whichthe central guide or eye is stationary, an edge wire is usually requiredto hold out the e ge while weaving because of the hard pull of thestationary guide or eye in said shuttle. With shuttles embodying thepresent invention, however, this wire is unnecessary in making a frilledge because as the eye or guide 26 is yieldingly mounted, it breaks thesudden throw of the thread in the shuttle against the edge of the web.At the same time the filling is placed in the web at the same tension asit would with a stationary guide because of the tension springs 18 and19.

Although I have disclosed the invention as embodied in the type ofshuttle shown it may be used equally as well in a circu r shuttle.

Having thus set forth the nature of my invention, what I claim is:

1. A loom shuttle comprising a body, a guide for the thread as it leavesthe shuttle mounted in the front portion of the body, and means allowingadjustment of said guide longitudinally of said front portion and forsecuring it in adjusted position.

2. A loom shuttle comprising a body, a guide for the thread as it leavesthe shuttle adapted for longitudinal movement in the front portion ofthe bod and means for adjustably and yielding y mounting the guide.
